[0052] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0053] The maintenance operation monitoring method provided by the embodiments of the present application can be applied to, for example, Figure 1The application environment shown. Among them, the elevator monitoring terminal 102 can collect data information of the elevator 101, the elevator monitoring terminal 102 can be integrated into the elevator 101, or can be independently set and communicated with the elevator 101; The elevator monitoring terminal 102 communicates with the center server 103 through the network. The data storage system can store the data required by the center server 103 for processing. The data storage system can be integrated on the center server 103, or can be placed on the cloud or other network servers. The maintenance terminal 104 communicates with the center server 103 through the network. In the application scenario of the present disclosure, the elevator monitoring terminal 102 receives the current maintenance work content of the elevator 101 sent by the center server 103, and the elevator monitoring terminal 102 monitors the maintenance work of the maintenance personnel on the elevator 101 according to the current state data of the elevator 101 obtained; When the maintenance work is monitored to have risks, the alarm information corresponding to the risks is sent to the center server 103, and the alarm information is forwarded to the maintenance terminal 104 by the center server 103, and the alarm information is displayed to the maintenance personnel by the maintenance terminal 104. Among them, the elevator monitoring terminal 102 and the maintenance terminal 104 can be, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The center server 103 can be realized by an independent server or a server cluster composed of multiple servers.

[0054] In one embodiment, as shown in Figure 2 , a maintenance work monitoring method is provided. Taking the elevator monitoring terminal 102 in Figure 1 as an example, the method includes the following steps:

[0055] Step 201, receiving the current maintenance work content of the elevator sent by the center server; The current maintenance work content includes each state of the elevator under the current maintenance work content, the change order of each state and the duration range of each state.

[0056] Among them, the current maintenance work content corresponds to the current maintenance work that the maintenance personnel needs to perform.

[0057] Among them, the duration range of each state is composed of the shortest duration and the longest duration of each state.

[0058] Exemplarily, the elevator monitoring terminal 102 receives the current maintenance work content sent by the center server 103 through the wireless communication network. The current maintenance work content is automatically generated by the center server 103 according to the preset maintenance plan, which can represent the various states of the elevator under the current maintenance work, the change order of each state and the duration range.

[0059] In step 202, current state data of the elevator is acquired, and risk information of the current maintenance operation is determined according to the current state data and the current maintenance operation content.

[0060] The current state data includes maintenance switch information of each part of the elevator, hall door and car door state of each floor, current floor, running direction, weighing information, fast / slow car state, current of each component, voltage and communication state, etc.

[0061] For example, the elevator monitoring terminal 102 can acquire the current state data of the elevator directly through the elevator 101, or can acquire the current state data of the elevator through various sensors, and compare the current state data with the current maintenance operation content to determine whether the current state data meets the various states, the change order or the duration range of each state in the current maintenance operation content, and then determine whether the process of the maintenance personnel in the maintenance operation meets the current operation specification, so as to conclude whether there is a risk in the current maintenance operation of the maintenance personnel, i.e. the risk information.

[0062] In step 203, when it is determined that there is a risk in the current maintenance operation based on the risk information, an alarm information is generated and sent to the central server, and the central server is configured to send the alarm information to the maintenance terminal.

[0063] The alarm information includes specific conditions of the current risk.

[0064] For example, when the risk information indicates that there is a risk in the current maintenance operation, i.e. the process of the maintenance personnel in the maintenance operation does not meet the current operation specification, the elevator monitoring terminal 102 will automatically generate corresponding alarm information, and send the alarm information to the central server through the wireless communication network, so that the central server forwards the alarm information to the maintenance terminal to remind the maintenance personnel. Further, in order to reduce the communication delay, the elevator monitoring terminal can also directly send the alarm information to the maintenance terminal through the communication network.

[0065] In the above maintenance operation monitoring method, by acquiring the current state data of the elevator and comparing it with the current maintenance operation content, when the current state of the elevator does not meet the state change information in the current maintenance operation content, it is determined that there is a risk in the current maintenance operation, and an alarm information is generated to remind the maintenance personnel. Further, the safety in the maintenance operation process is ensured, and the maintenance personnel is prevented from being in danger.

[0066] In one embodiment, as shown in Figure 3 The step 202 of determining the risk information of the current maintenance operation according to the current state data and the current maintenance operation content can also be implemented by the following steps:

[0067] Step 2021, comparing the current state data and the current maintenance work content to obtain difference information between the current maintenance work and the current maintenance work content;

[0068] Step 2022, determining the risk information of the current maintenance work according to the difference information.

[0069] Exemplarily, the current state data of the elevator is obtained, and the current running state of the elevator can be analyzed according to the current state data. Based on the running state of the elevator that may appear under the corresponding work in the received current maintenance work content, the conversion sequence of each state and the time range that each state may last, it is determined whether the running state of the current elevator is planned to appear, whether the conversion of the state is correct, and whether the duration of the state is appropriate, etc. to obtain the corresponding difference information, and to determine the risk information of the current maintenance work from the difference information.

[0070] In this embodiment, the maintenance work is monitored according to the received current maintenance work content, and it can be determined whether the maintenance work of the maintenance personnel is performed according to the predetermined plan, so that the process of the current maintenance work can be effectively monitored to ensure the safety of the maintenance work.

[0071] In one of the embodiments, the step 2022 of determining the risk information of the current maintenance work according to the difference information can also be implemented by the following steps:

[0072] Step one, determining the abnormal type of the current maintenance work according to the difference information; the abnormal type includes the omission of the maintenance work step, the sequence error of the maintenance work step and the abnormal increase of the maintenance work step;

[0073] Step two, determining the risk information of the current maintenance work according to the abnormal type.

[0074] Exemplarily, according to the difference between the current state of the elevator and the maintenance work content in the difference information, it is determined whether there is an abnormal type such as missing steps, sequence error or abnormal increase of steps in the maintenance work of the maintenance personnel, wherein the duration of a certain state of the elevator is not enough or the duration is too long, which will be determined as sequence error; according to the abnormal type, the risk information of the current maintenance work can be determined, which contains specific abnormal information.

[0075] In this embodiment, the abnormal situation of the maintenance personnel in the maintenance work is obtained according to the current maintenance work content, the corresponding alarm information is generated from the abnormal situation, which can better remind the maintenance personnel of the specific error situation, so as to ensure the safety of the maintenance personnel.

[0076] In one of the embodiments, the step 203 generates the alarm information when it is determined that the current maintenance operation has risks based on the risk information, and the step 203 can be implemented by the following steps:

[0077] Step one, determine the risk level corresponding to the current maintenance operation based on the risk information.

[0078] Step two, generate the corresponding alarm information based on the risk level.

[0079] In one of the embodiments, the step two generates the corresponding alarm information based on the risk level, and the step two can be implemented by the following steps:

[0080] Generate the corresponding alarm information according to the positive correlation between the risk level and the number of alarm forms.

[0081] The alarm forms include text form, vibration form, sound form, and light form, etc.

[0082] For example, each risk information represents different risk situations, each risk situation has different risk levels, and each risk level represents different risk degrees, so different risk levels of risk information need different alarm information. Each alarm information at least contains text information, which is displayed on the maintenance terminal to remind the user; according to the rising of the risk level, the alarm information will first increase the vibration information that generates vibration on the maintenance terminal, and then increase the sound information and light information generated by the maintenance terminal. For example, when the risk level is the lowest level, the elevator monitoring terminal only generates the alarm information in the text form to remind the maintenance personnel; when the risk level is the second level, the elevator monitoring terminal generates the alarm information in the vibration form in addition to the alarm information in the text form; when the risk level is the highest level, the alarm information contains text information, vibration information, sound information, and light information.

[0083] In the above embodiments, different alarm information is generated according to different risk levels, and the alarm information reminds the maintenance personnel of the risk situation in multiple forms of information, so that the maintenance personnel can intuitively feel the risk level of the current maintenance operation, and avoid the maintenance personnel making mistakes and causing safety accidents.

[0084] In one of the embodiments, the running control right of the elevator is acquired when the risk level exceeds the preset level threshold, to prevent the elevator from running.

[0085] For example, when the risk level exceeds the preset level threshold, i.e., the current maintenance operation has a risk of a major safety accident, the elevator monitoring terminal will acquire the running control right of the elevator to prevent the elevator from running without eliminating the risk.

[0086] In this embodiment, when the risk level reaches the preset threshold, the elevator monitoring terminal will urgently control the elevator to avoid the elevator running in the case of not eliminating the risk and causing a safety accident, thereby ensuring the safety of the maintenance personnel.

[0087] In another embodiment, as shown in Figure 4 , a maintenance operation monitoring method is provided, which includes the following steps in this embodiment:

[0088] Step 401, receiving the current maintenance operation content of the elevator sent by the center server.

[0089] Step 402, obtaining the current state data of the elevator, comparing the current state data and the current maintenance operation content, and obtaining the difference information between the current maintenance operation and the current maintenance operation content.

[0090] Step 403, determining the abnormal type of the current maintenance operation according to the difference information, and determining the risk information of the current maintenance operation according to the abnormal type.

[0091] Step 404, determining the risk level corresponding to the current maintenance operation based on the risk information.

[0092] Step 405, generating corresponding alarm information according to the positive correlation between the risk level and the number of alarm forms, and sending the alarm information to the center server.

[0093] Step 406, obtaining the operation control authority of the elevator in the case that the risk level exceeds the preset level threshold, and preventing the elevator from running.

[0094] Exemplarily, the elevator monitoring terminal receives the current maintenance operation content sent by the center server, and can obtain the current state data of the elevator through a sensor, compare the current maintenance operation content and the current state data, and obtain the process difference information between the current maintenance operation and the current maintenance operation content of the maintenance personnel; based on the difference information, the risk information existing in the current maintenance operation is determined, and the risk level of the current maintenance operation is determined according to the risk information; according to the risk level, the corresponding number of alarm forms is generated, which is sent to the center server and forwarded to the maintenance terminal by the center server; at the same time, if it is judged that the risk level exceeds the preset threshold, the operation control authority of the elevator is urgently obtained to prevent the elevator from running and causing a safety accident.

[0095] In order to facilitate those skilled in the art to understand the embodiments of the present application, the present application is described in the following specific examples combined with the drawings. As Figure 5 shown, the maintenance operation process of the elevator video box for repairing the car roof includes:

[0096] Step 501, opening the maintenance switch in the car;

[0097] Step 502, press the slow speed button;

[0098] Step 503: When the car top is level with the hall door, release the slow speed button;

[0099] Step 504: Open the hall door and enter the top of the sedan chair;

[0100] Step 505: Turn on the emergency stop switch;

[0101] Step 506: Turn on the inspection switch on the car top;

[0102] Step 507: After the maintenance is completed, turn off the maintenance switch on the car top;

[0103] Step 508: Turn off the emergency stop switch;

[0104] Step 509: Leave the top of the sedan chair and close the hall door;

[0105] Step 510: Turn off the inspection switch inside the car to complete the maintenance work.

[0106] For example, in step 401, the elevator monitoring terminal receives data sent by the central server and... Figure 5 The current maintenance work content corresponds to the maintenance work process. The current maintenance work content may include the replacement sequence between the inspection switch and the slow speed status in the car, the status data when the car top is aligned with the hall door, etc.; the elevator monitoring terminal obtains the current status data of the elevator through sensors to monitor the maintenance work. For example, the alignment of the car top with the landing door is determined by the maintenance personnel's perception. If the maintenance personnel's perception is inaccurate and there is a significant distance difference between the car top and the landing door, there is a risk of falling for personnel entering the car top. In this case, the elevator monitoring terminal will generate an alarm message to remind the maintenance personnel when it detects that the landing door is open and there is still a significant distance difference between the car top and the landing door. Alternatively, if maintenance personnel enter the car top and it is detected that the emergency stop switch and the car top inspection switch are not activated, even if the landing door is closed and the car inspection switch is closed, the elevator monitoring terminal will still consider the maintenance personnel to be still on the car top. In this case, the elevator monitoring terminal will consider it a high-risk situation and urgently acquire elevator operation control authority to prevent the elevator from operating and causing harm to the maintenance personnel. Only after the maintenance personnel inform the elevator monitoring terminal personnel through the maintenance terminal and leave the car top will the elevator operation control authority be released.

[0107] In this embodiment, by acquiring the current state data of the elevator and comparing it with the current maintenance work content, in the case that the current state of the elevator does not conform to the state change information in the current maintenance work content, it is determined that the current maintenance work has risks and corresponding risk levels, thereby generating corresponding alarm information to directly remind the maintenance personnel; at the same time, a risk level threshold is set, which can control the elevator operation in an emergency, thereby ensuring the safety during the maintenance work and avoiding the maintenance personnel from being in danger.

[0108] It should be understood that, although each step in the flowchart involved in each embodiment as described above is displayed in sequence according to the arrow, these steps are not necessarily executed in sequence according to the arrow. Unless otherwise specified herein, there is no strict sequence limitation for the execution of these steps, and these steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each embodiment as described above can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or steps or stages in other steps.

[0109] Based on the same inventive concept, the embodiments of the present application also provide a maintenance work monitoring system for implementing the above-mentioned maintenance work monitoring method. The implementation scheme for solving the problem provided by the system is similar to the implementation scheme described in the above method, so the specific limitations in one or more maintenance work monitoring system embodiments provided below can refer to the limitations of the maintenance work monitoring method described above, which will not be repeated here.

[0110] In one embodiment, as shown in Figure 6 A maintenance work monitoring system is provided, including an elevator monitoring terminal 601, a center server 602 and a maintenance terminal 603, the center server 602 is in communication connection with the elevator monitoring terminal 601 and the maintenance terminal 603 respectively, wherein:

[0111] The center server 602 is configured to send the current maintenance work content of the elevator to the elevator monitoring terminal 601; the current maintenance work content includes each state of the elevator under the work corresponding to the current maintenance work content, the change order of each state and the duration range of each state;

[0112] The elevator monitoring terminal 601 is used to receive the current maintenance work content sent by the central server 602; obtain the current status data of the elevator; determine the risk information of the current maintenance work based on the current status data and the current maintenance work content; and generate alarm information and send the alarm information to the central server 602 if the current maintenance work is determined to be risky based on the risk information.

[0113] The central server 602 is also used to receive alarm information sent by the elevator monitoring terminal 601 and send the alarm information to the maintenance terminal 603.

[0114] In this embodiment, the elevator monitoring terminal obtains the elevator's current status data and compares it with the current maintenance work content sent by the central server. If the elevator's current status does not match the status changes or other information in the current maintenance work content, it determines that the current maintenance work poses a risk, generates an alarm message, and sends it to the central server. The central server then forwards the alarm message to the maintenance terminal to alert maintenance personnel. This ensures safety during maintenance operations and prevents maintenance personnel from falling into danger.

[0115] In one embodiment, such as Figure 7 The diagram shown is a flowchart of a maintenance operation monitoring system, which includes the following steps:

[0116] Step 701: The central server sends the maintenance plan to the maintenance terminal;

[0117] The maintenance plan includes the elevators to be maintained, the maintenance dates, and the maintenance content. The maintenance content includes the maintenance operation steps for multiple maintenance items and information on potential hazards.

[0118] Step 702: The maintenance terminal displays the received maintenance plan and displays the specific maintenance content in response to the maintenance items selected by the maintenance personnel.

[0119] Step 703: The maintenance terminal sends the identifier of the current maintenance project selected by the maintenance personnel to the central server.

[0120] Step 704: After receiving the identifier of the current maintenance operation, the central server sends the current maintenance operation content corresponding to the identifier to the elevator monitoring terminal.

[0121] It should be noted that the central server can also send all maintenance work content to the elevator monitoring terminal at the same time during step 701. When the maintenance personnel select the current maintenance item, the server will forward the current maintenance item's marker to the elevator monitoring terminal.

[0122] Step 705: The elevator monitoring terminal monitors the current maintenance work based on the received current maintenance work content.

[0123] Step 706, when the elevator monitoring terminal finds that the current maintenance work has risks, corresponding alarm information is generated.

[0124] Step 707, when the risk level reaches the corresponding level, the elevator monitoring terminal will issue sound and light alarm information to remind the maintenance personnel; when the risk level reaches the preset threshold, the elevator monitoring terminal will also obtain the running control authority of the elevator to prevent the elevator from running.

[0125] At the same time as step 707, step 708 is also performed, in which the elevator monitoring terminal sends the alarm information to the center server.

[0126] Step 709, the center server forwards the received alarm information to the maintenance terminal.

[0127] Step 710, the maintenance terminal issues corresponding text, vibration, sound and light alarm information according to the received alarm information.

[0128] Step 711, the maintenance terminal displays the current abnormal information and the correct processing method according to the alarm information.

[0129] It should be noted that the center server in this embodiment can also store the maintenance work content and the alarm information, and provide corresponding query services.

[0130] In this embodiment, according to the maintenance work content and the current state of the elevator, it is judged whether the maintenance personnel performs the elevator maintenance according to the normal operation process. The system will process according to the danger degree of the operation. For high-level cases, the elevator running can be controlled to ensure the safe performance of the maintenance work.

[0131] Based on the same inventive concept, the present embodiment also provides a maintenance work monitoring device for implementing the maintenance work monitoring method described above. The implementation scheme of the device for solving the problem is similar to the implementation scheme described in the above method, so the specific limitations in one or more maintenance work monitoring device embodiments provided below can refer to the limitations of the maintenance work monitoring method in the foregoing, which will not be repeated here.
